Breath ¹³CO₂ enrichments (A) and exogenous carbohydrate oxidation rates (B) during exercise without ingestion of carbohydrate (WAT), with the ingestion of glucose (GLU), with the ingestion of glucose and fructose (GLU + FRU), or with the ingestion of glucose and sucrose (GLU + SUC). Data were analsysed with a two-way repeated measures ANOVA (time-treatment). Data are presented as means ± SEM. N = 10. a, denotes GLU significantly different from WAT; b, denotes GLU + FRU significantly different from WAT; c, denotes GLU + SUC significantly different from WAT; d, denotes GLU + FRU significantly different from GLU; e, denotes GLU + SUC significantly different from GLU (p < 0.05).
